Bovine dystocia due to malformation of the fetus. (a) Conjoined twins (cephalothoracopagus monosymmetros) as in utero; (b) Same as (a) after being released from the uterus. The fetuses were extracted after euthanasia of the dam who also suffered from hydrallantois; (c) Contracted calf in utero. Part of the uterine wall and fetal membranes have been removed. The case is likely to represent a case of arthrogryposis multiplex congenita; (d) Ischiopagus tetrapus
